I/UrlLauncher(17669): component name for (url) is null

Why does it throw an error and give me the link is empty even though the link exists? And when I use launch (url) alone, the link opens without any problems.

enter image description here

 String StateUrl = 'View App' ;
 var url = 'https://www.youtube.com/watch?v=-k0IXjCHObw' ;
body: Column(
        children: [
          Text(StateUrl),
          Center(
            child: ElevatedButton.icon(
                onPressed: () async{
                  try {
                    await canLaunch(url) ?
                    await launch(url):
                    throw 'Error';
                  } catch(e){
                    setState(() {
                      StateUrl = e.toString() ;
                    });
                  }
                },
                icon: const Icon(FontAwesomeIcons.link),
                label:  const Text('View Url')
            ),
          ),
        ],
      ),

Performing hot reload:

D/EGL_emulation(17669): app_time_stats: avg=17852.65ms min=658.78ms max=35046.52ms count=2 I/UrlLauncher(17669): component name for https://www.youtube.com/watch?v=-k0IXjCHObw is null D/EGL_emulation(17669): app_time_stats: avg=8279.72ms min=8279.72ms max=8279.72ms count=1
